For procurement managers and R&D professionals in demanding industrial sectors, selecting the correct elastomer is paramount to product performance and longevity. Chlorosulfonated Polyethylene, commonly known as CSM, stands out as a highly versatile synthetic rubber offering an exceptional combination of properties. As a leading CSM elastomer manufacturer and supplier, we aim to guide you through the nuances of choosing the right CSM grade for your specific applications.

CSM is synthesized by modifying polyethylene, introducing chlorine and sulfonyl chloride groups onto the polymer backbone. This chemical transformation imbues the material with remarkable resistance characteristics that far surpass those of many conventional elastomers. Key among these are its superior resistance to ozone, atmospheric aging, chemical attack (especially from oxidizing agents), heat, and flame. This makes CSM an ideal candidate for applications exposed to harsh environmental or chemical conditions.

When evaluating CSM for purchase, understanding the critical specifications is crucial. You'll frequently encounter parameters such as chlorine content and Mooney viscosity. Typically, CSM grades contain around 27-45% chlorine. A higher chlorine content generally enhances flame resistance and oil resistance. Mooney viscosity, measured at 100°C, indicates the rubber's processability and physical properties. For instance, grades like CSM 40, 3304, and 3305 are common, each offering distinct performance profiles. CSM 40, for example, is often used for hard coatings and adhesives, while higher Mooney viscosity grades like CSM 3305 are suited for automotive hoses and specialty rubber products.

The applications for CSM are extensive and diverse. In the automotive industry, its resistance to heat, oil, and weathering makes it invaluable for hoses, seals, and engine components. For wire and cable insulation, CSM provides excellent dielectric properties along with flame retardancy and abrasion resistance. Beyond these, CSM finds use in protective coatings for chemical plants, roofing membranes, industrial rollers, and even in certain types of footwear and fabric coatings due to its excellent durability and water resistance.
